The jury in the trial of former Anglo Irish Bank chief executive David Drumm has been sent home again as one of its members is not available.

The jurors began their deliberations on Tuesday and have deliberated for almost four hours so far.

They were due to continue yesterday but the court heard one juror was "indisposed".

This morning, Judge Karen O'Connor told the remaining 11 jurors that the person remained "indisposed".

However she said the juror had been in contact with the Courts Service and had indicated they would be available on Tuesday.

The judge said it was "most unfortunate", but this was what could happen during in a trial and there was nothing that could be done about it.

The jury will resume deliberations on Tuesday morning.

Judge O'Connor reminded them they were at a critical stage.

They had started deliberations she said and matters were in their hands now.

This is day 84 of the trial, which began in January.

Mr Drumm has pleaded not guilty to conspiring with others to dishonestly make Anglo's balance sheet look better by €7.2 billion between March and September 2008.

He also denies knowingly presenting false figures to the market in December 2008.

The prosecution says he did this deliberately and dishonestly to induce people to invest in or leave their money in Anglo, even when he and others knew it was going down the tubes.

Mr Drumm says the transactions were not dishonest and were legitimate balance sheet management carried openly and transparently while trying to protect the bank.
